8.1 Alarms
Note ! To reset alarms, see paragraph 6.6.1.
In the following table, the Code is visible only from serial line.
Code Error message shown
on the display
Sub-code Description
0 No alarm Condition: No alarm present
1 Overvoltage
Condition: DC link overvoltage alarm due to energy recovered from the motor.
The voltage arriving at the drive power section is too high compared to the maximum threshold relating to the PAR 560
Mains voltage parameter setting.
Solution:
- Extend the deceleration ramp.
- Use a braking resistor between terminals BR1 and BR2 to dissipate the recovered energy
- Use the
Vdc Control function
2 Undervoltage
Condition: DC link undervoltage alarm.
The voltage arriving at the drive power section is too low compared to the minimum threshold relating to the 560
Mains voltage parameter setting due to:.
- the mains voltage being too low or overextended voltage drops.
- poor cable connections (e.g. loose contactor terminals, inductance, filter, etc. ).
Solution: Check the related connections of the drive power supply and its correct range.
3 Ground fault Condition: Ground short circuit alarm
Solution:
- Check drive and motor wiring.
- Check that the motor is not grounded.
4 Overcurrent
Condition: Instantaneous overcurrent protection intervention alarm.
This may be due to the incorrect setting of current regulator parameters or a short circuit between phases or ground
fault on the drive output.
Solution:
- Check the current regulator parameters
- Check wiring towards the motor
5 Desaturation Condition: Instantaneous overcurrent in the IGBT bridge alarm.
Solution: Switch the drive off and then switch it on again.
If the alarm persists, contact the technical service centre.
6 MultiUndervolt
Condition: The number of attempted automatic restarts after the Undervoltage alarm has exceeded the set PAR 4650
UVRep attempts value in the PAR 4652 UVRep delay time.
Solution: Too many Undervoltage alarms.
Adopt the proposed solutions for the Undervoltage alarm.
7 MultiOvercurr
Condition: 2 attempted automatic restarts after the Overcurrent alarm within 30 seconds. If more than 30 seconds
pass after the Overcurrent alarm was generated, the attempt counter is reset.
Solution: Too many Overcurrent alarms. Adopt the proposed solutions for the Overcurrent alarm.
8 MultiDesat
Condition: 2 attempted at automatic restarts after the Desaturation alarm within 30 seconds. If more than 30 seconds
pass after the Desaturation alarm was generated, the attempt counter is reset.
Solution: Too many Desaturation alarms.
Adopt the proposed solutions for the Desaturation alarm.
9 Heatsink OT Condition: Heatsink temperature too high alarm
Solution:
- Verify the correct operation of the cooling fan.
- Check that the heatsinks are not clogged
- Check that the openings for the cabinet cooling air are not blocked.
10 HeatsinkS OTUT Condition: IGBT modules temperature too high or too low alarm
